摘要 目的研究大豆异黄酮对妇女骨形成和骨吸收的影响,探讨大豆异黄酮预防妇女骨质疏松的量效关系。方法选择大豆异黄酮与妇女尿中脱氧吡啶酚(Dpyr)和血浆骨碱性磷酸酶(BAP)的随机和类随机对照试验。采用Meta分析方法进行分析。结果11个研究共797名观察对象纳入分析。Dpyr指标总体比较结果[0.02nmol/mmol肌酐,95%CI:-0.09~0.14,P=0.68,Meta分析结果揭示干预组和对照组间差异无统计学意义。将干预时间≤12周和摄入剂量≥90mg/d的研究纳入分析,总体比较结果分别为-0.46nmol/mmol,95%CI:-0.88~0.04,P=0.03和-0.43nmol/mmol,95%CI:-0.08~0.06,P=0.02,Meta分析结果揭示干预组均显著低于对照组。BAP指标总体比较结果[-3.51IU/L95%CI(-3.88,-3.14),p≤0.00001],Meta分析结果揭示干预组显著高于对照组。将摄入剂量60~90mg/d、≥90mg/d和干预时间≤12周的研究纳入分析,总体比较结果分别为(-0.57IU/L,95%CI:-1.06~-0.08,P=0.02)、(-7.46IU/L,95%CI:-8.03~6.89,P<0.00001)和(-6.37IU/L,95%CI:-6.94~5.79,P<0.0001)。Meta分析结果揭示干预组均显著高于对照组。结论大豆异黄酮具有抑制妇女骨吸收,促进骨形成的作用,在摄入剂量≥60mg/d或干预时间≤12w时即有显著结果。
